Specification for-ming part of Letters Patent No. 177,449, dated May 16, 1876; application tiled March 1s', 1876.

To all whom t may concern: Y

Be it known that I, PETER M. ANDRIOT, of

Oxi'ord,'in the county of Butler and State of Ohio, have invented a new and valuable Im provement in Mortisingand Tenoning Machine; and I do hereby declare that 'the fol-l lowing is a full, clear, and exact description ofthe construction and operation Ot' the saine, reference being had to the annexed drawings, making a part of this specitication,I and to the letters and figures of reference markedthereon.

produced, and which is adapted for use in all.

wood-working shops, as will be hereinafter more fully set forth.

In the annexed drawings, A represents the.

frame-work of my machine, constructed in any suitable manner to contain the various working parts. On the front sid'e of` the machine, at or near'the center, is an arched standard, B, upon which slides a head or `vertical frame, C, backward and forward, it being moved from the rear side by means of a screwshaft, a, and when properly adjusted fastened by a bolt and nut, a2. 011 top vot the frame C are two springs, D D, Ot' desired strength, one being used for light work, and both together for heavy Work. They are connected to the shaft b, which raises the chisel ol by means ot long links e,`and.they may be attached andV detached at will. The tenoning-chisel d is constructed with double square corners d1 of sufficient width to cut the shoulder at the same timeas the flat or 'main part ofthe chisel cuts the tenonwithout the use of a saw. This chisel is attached to the lower end of the shat't b; and the tenon may be cut from 'either side ofthe chisel. The shaft b'has 'an arm, b1, from which a rod, b2, connects with a treadle, E, for operating the chisel. G is the table moved out and in on a'frame, H, by means of a screwshaft, f, and provided with a ledge or flange, h, along its inner edge, said flange being, however, cut away at the point where the chisel operates.l

ln transverse slots on the table G are placed two vises,'I I, operated byscrew-shat'ts f f for holding the work lirmly against the ange h on the table. The table-frame H is held to the main frame A by two bolts, m m', passing through a slot in a vertical bar on said main i frame; and the lower bolt m passes through a curved slot, nain the table-frame H, thus admitting of the table being adjusted at any angle desired, as well as raised or loweredas required, which adjustments are effected by means of the screw-shaft p, as shown.

It will thus be seen that the machine can vbe used for mitering as well as t'orstraight work.

The change from tenoning to mortising is effected by simply changing chisel. On each side of the frame or head G is a socket, r, through which is passed ashatt, s, carrying at its lower end a dog, t, which may be let down to aid in holding the work, and is then fastened by a set-screw, c, in the socket.

Through the standard B is passed-a horizontal shaft, J, operated by crank or treadle, as desired, and carrying a bit -at its front end for PETER MAURICE ANDRIOT.
